DVO Cross Colour

ch-dvo-effects-dvo-cross-colour-intro

 

Cross Colour (also known as Chroma Crawling) is a defect that results from crosstalk between the chrominance and luminance components of a composite video signal (PAL or NTSC). Once a video signal has been in the composite domain, this defect is not easily removed.

Parameters

Enable

ch-dvo-effects-dvo-line-sync-enable

 

When enabled, DVO Cross Colour will process the input as per the settings described below.

Aggressiveness

ch-dvo-effects-dvo-cross-colour-aggressiveness

 

Allows the tuning of the degree of removal.

 

dv_alert

If we increase these parameters too much we increase the possibility of introducing artifacts.

Spatial

When the Temporal setting is decreased, The Spatial control may be increased instead to remove cross-colour at the expense of slight spatial chroma bleeding.

Temporal

Increase for maximum cross-colour removal. Reduce if temporal chroma bleeding becomes too intrusive.
